A DWELLING OF (DANGEROUS) SIMPLICITY!

A trap within a trap awaits the newly regenerated and vulnerable Fifth Doctor, helped (by the caring Tegan and Nyssa) and hindered (by the genius mathematical mind of the captured Adric) in an all-new battle with The Master within the mysterious olde world castle at Castrovalva - a story imaginatively crafted by Christoper H. Bidmead that was 'absolutely splendid' in launching Peter Davison in the title role, captured in this great art by Marshall Tankersley.
